Ella Mae Morse

"Cow Cow Boogie” was written for the 1942 Abbott & Costello film Ride’ Em 
Cowboy, which included Ella Fitzgerald as a cast member. The song was
recorded by 17- year-old Ella Mae Morse with the music of Freddie Slack
& his Orchestra.  It was the first release by Capitol Records and their first
million seller. Ella never obtained a huge following, but continued to record
until 1957. She died of respiratory failure in 1999 at age 75.

Elvis was in basic training at Fort Hood Army post in Texas when this
song hit the top of the Billboard chart. It was recorded as part of the
soundtrack for the motion picture King Creole. It also went to number
two for two weeks on the R&B chart. It was the first rock and roll single
to earn the RIAA designation of Gold Record.
